Specifically, in the conventional display Panel (Panel) design, the Seal adhesive (Seal) design is determined according to the peripheral layout of the display Panel, and because the peripheral design of the special-shaped Seal adhesive product is different from that of products such as conventional mobile phones and vehicle-mounted equipment, and the like, seal adhesive is only required to be sealed at the periphery of the Panel, when VR products need split-screen display, the peripheral Seal adhesive is usually used as a special-shaped structure for meeting the requirements of customers and the requirements of peripheral design placement, and the Seal adhesive is internally communicated to form a structural model for integrally driving liquid crystals.
According to the display panel provided by the embodiment of the disclosure, the second frame sealing glue 32 connected with the first frame sealing glue 31 is arranged on the inner side of the first frame sealing glue 31 around the edge of the display panel, the glue frame formed by the first frame sealing glue 31 is divided into a plurality of glue frame areas, the glue frame areas are adhered to the array substrate 1 and the color film substrate 2 to form a plurality of independent accommodating spaces 4 for filling the liquid crystal layer 5, interaction of Liquid Crystal (LC) molecules in different accommodating spaces 4 can be effectively isolated, meanwhile, supporting effects of the second frame sealing glue 32 between the array substrate 1 and the color film substrate 2 are matched, various optical defects such as nonuniform liquid crystal volume, nonuniform liquid crystal Gap (Cell Gap) and the like in a liquid crystal box caused by film layer difference of different screens can be improved, high-specification display of display device products such as VR products is guaranteed, meanwhile, the problem of optical reliability of upper and lower screens of the products is solved, and the optical performance of the products is improved.
In this embodiment, the second frame sealing glue 32 is disposed between two longitudinally opposite first frame sealing glue 31 and is connected to two longitudinally opposite first frame sealing glue 31.

In this embodiment, besides the frame sealing glue disposed at the edge of the display panel, the frame sealing glue is disposed at the middle of the display panel to form a plurality of liquid crystal boxes that are sealed independently, so as to prevent liquid crystal from flowing between different liquid crystal boxes, and the supporting effect of the second frame sealing glue 32 is utilized to reduce the effect of the second frame sealing glue on the atmosphere, so that the optical uniformity of the display panel can be improved.

In this embodiment, as shown in fig. 4, the second frame sealing glue 32 is one, separates the glue frame formed by the first frame sealing glue 31 into two glue frame areas, so as to form two closed accommodating spaces 4 by being attached to the array substrate 1 and the color film substrate 2, and divides the display panel into an upper screen and a lower screen, wherein the upper screen is a screen (DO side) near the top of the display panel, and the lower screen is a screen (DP side) near the bottom of the display panel (near the integrated circuit binding area FPC). The second frame sealing glue 32 can form a structure with uniform upper and lower bottom surfaces, and ensures the optical uniformity of the upper screen and the lower screen.
In addition, in this embodiment, the second frame sealing glue 32 disposed on the inner side of the first frame sealing glue 31 and connected with the first frame sealing glue 31 directly separates the whole frame into a plurality of frame sealing areas, so that compared with the case sealing areas disposed around the edge of each split screen sub-screen, the glue spreading time can be effectively shortened, the area of the whole screen display area (gaps exist between adjacent frame sealing areas when the glue is respectively disposed) can be increased, and the uniformity of the whole screen display can be ensured.
In other embodiments, a plurality of second frame sealing adhesives 32 may be disposed at intervals along the longitudinal direction of the display panel according to the number of split screens, for example, the display panel includes three display screen areas of an upper screen, a middle screen and a lower screen, so two second frame sealing adhesives 32 may be disposed at intervals along the longitudinal direction of the display panel to form three liquid crystal layer areas.
In some embodiments, the volume of each accommodating space 4 is the same, and equal amount of liquid crystal is filled in each accommodating space 4 to form a plurality of uniform display areas, so that the optical uniformity of different display areas is ensured, the problem of non-uniform liquid crystal gaps during double-screen display is solved, and the optical performance of a product is improved.
In other embodiments, the volume of each accommodating space 4 may be different, so long as the pixel density after filling the liquid crystal is the same, so that the optical uniformity of different display areas can be ensured.
In some embodiments, the width of the second frame sealing glue 32 is greater than the width of the first frame sealing glue 31, so that the second frame sealing glue 32 can form a stable support between the array substrate 1 and the color film substrate 2, and avoid various optical defects caused by interaction between the bottom film layer structures of the array substrate 1 and the color film substrate 2 and the atmospheric pressure.
In some embodiments, the first frame sealing glue 31 and the second frame sealing glue 32 are coated on the color film substrate 2. Since the liquid crystal is generally instilled on the array substrate 1, in this embodiment, the frame sealing glue coating and the liquid crystal instilling can be performed by using the color film substrate 2 and the array substrate 1 respectively, so as to improve the processing efficiency of the display panel.
In some embodiments, as shown in fig. 4, the accommodating space 4 filled with the liquid crystal layer 5 forms a display area (AA area), a virtual area 6 (Dummy area) is disposed around the periphery of the display area, and a rubber frame area is disposed around the periphery of the virtual area 6. In this embodiment, the glue frame area is disposed at the periphery of the virtual area 6, and virtual pixels of the virtual area 6 can be connected with pixels (for example, OLED pixels) in the display area through cables to perform optical matching, so as to ensure reliable display of the display area.
In some embodiments, as shown in fig. 2 and fig. 3, at least one first support column 11 (Array SMT PS) is disposed on a side of the Array substrate 1 facing the color film substrate 2, at least one second support column 21 (CF PS) in one-to-one butt joint with the first support columns 11 is disposed on a side of the color film substrate 2 facing the Array substrate 1, and at least one group of first support columns 11 and second support columns 21 in butt joint with each other are disposed in each accommodating space 4, so that a stable support can be formed when the bottom film structures of the Array substrate 1 and the color film substrate 2 interact with atmospheric pressure, morphology of each accommodating space 4 is prevented from changing, uniformity of liquid crystal gaps in each accommodating space 4 is ensured, and optical performance of the display panel is further improved.
As shown in fig. 2, the display panel further includes a Black Matrix (BM) 7 disposed above the liquid crystal layer 5 to prevent light leakage at the edges of the pixels; the black matrix 7 is provided with BM grooves 71 at positions corresponding to the first seal frame 31 to solve the problem of electrostatic transmission.
The display panel provided by the embodiment of the disclosure performs sub-screen internal sealing through the second frame sealing glue 32 arranged at the middle position of the array substrate 1 and the color film substrate 2, improves the optical uniformity of different sub-screens (upper screen and lower screen) of the split-screen VR product, ensures the space uniformity in the liquid crystal boxes of different sub-screens, ensures the equal dropping amount of liquid crystals in the liquid crystal boxes of different sub-screens, and improves the liquid crystal gap uniformity of the product.
The liquid crystal gap performance test experiment shows that the average level of the liquid crystal gap difference of the intercommunication structure inside the frame sealing glue is 0.07 μm, and the average level of the liquid crystal gap difference is 0.02 μm after the second frame sealing glue 32 is arranged to form an independent and closed liquid crystal box, the embodiment can improve the uniformity of the liquid crystal gap by about 150% (the average value calculated by taking the absolute value of the difference between the liquid crystal gaps of the upper screen and the lower screen is the relative difference between the liquid crystal gaps of the upper screen and the lower screen), and the yield of the improved product can be improved by 11.1%; in this embodiment, the second frame sealing glue 32 separates the glue frame formed by the first frame sealing glue 31 into a plurality of independently closed glue frame areas, and liquid crystal molecules are all filled in respective corresponding positions during the box, so that the optical uniformity of the upper screen and the lower screen of the product can be improved, and the optical performance test proves that the poor average level of the L127 brightness difference of the internal intercommunication structure of the frame sealing glue is 2.5%, while the poor average level of the L127 brightness difference is 0% in this embodiment, and the design uniformity is improved by 18.87% after the frame sealing glue isolates the liquid crystal molecules from flowing (the brightness difference of the upper screen and the lower screen is within 3% in the FOG state). According to the split screen VR device, the second frame sealing glue 32 is utilized to separate the liquid crystal interaction between the upper screen and the lower screen at the split screen position, so that the uniformity of the liquid crystal gap between the upper screen and the lower screen in the lower screen box is remarkably improved, the optical reliability of the product is greatly improved, and the poor optical reliability of the split screen VR product is improved.
The embodiment of the disclosure also provides a manufacturing method of the display panel, which comprises the following steps:
s101: coating a first frame sealing glue 31 and a second frame sealing glue 32 on the color film substrate 2 to form a plurality of glue frame areas, wherein the first frame sealing glue 31 is coated around the edge of the color film substrate 2, and the second frame sealing glue 32 is coated on the inner side of the first frame sealing glue 31 and is connected with the first frame sealing glue 31;
s102: dropping liquid crystal on the array substrate 1;
s103: and the color film substrate 2 and the array substrate 1 are paired and are attached together through the first frame sealing glue 31 and the second frame sealing glue 32.
Specifically, an array substrate 1 and a color film substrate 2 are provided, where the array substrate 1 and the color film substrate 2 may be transparent substrates such as a glass substrate, a quartz substrate, and a plastic substrate, and in this embodiment, the array substrate 1 is preferably a glass substrate.
As shown in fig. 5, after the PP-Clean unit is normally processed in the liquid crystal process ODF (One Drop Filling), the color film substrate 2 is painted, the painting start end of the SED unit frame sealing glue is set on the DP side, two longitudinally opposite first frame sealing glue 31 and a transverse first frame sealing glue 31 (the SED needle is finished at one time) are painted from the DP side through the SED process, so as to form a frame sealing body with an opening, then the second frame sealing glue 32 is painted at the split screen position (middle position), and then the transverse first frame sealing glue 31 is painted on the DO side so as to seal the frame sealing glue, so that two accommodating spaces 4 with identical bottom areas are formed in the upper split screen and the lower split screen. After the painting is finished, the frame sealing glue is coated on the color film substrate 2, when the liquid crystal is opposite to the box, the frame sealing glue fully covers the virtual area 6 of the color film substrate 2, the upper screen and the lower screen of the array substrate 1 drop liquid crystal with the same quality, and liquid crystal patterns (LC patterns) are formed by small drops, so that liquid crystal puncture is prevented. The first frame sealing glue 31 and the second frame sealing glue 32 are coated on the color film substrate 2, after liquid crystal is dripped on the array substrate 1, the array substrate 1 and the color film substrate 2 are attached, and finally, the attached array substrate 1 and the array substrate 1 are cured at high temperature to cure the frame sealing glue into a box, so that the complete display panel 10 is formed. After the alignment, the liquid crystal slowly diffuses in the corresponding accommodating space 4.
The display panel provided in the embodiment of the disclosure is mainly suitable for VR products with upper and lower split screens, for example, B6 VR products, in order to pursue better VR optical performance, the heights of the support columns are reduced to the limit, but due to the influence of the related process steps of the first support column 11, the uniformity level of the whole support column is not effectively improved, so as to manufacture VR split screen products with high requirements (as shown in fig. 1). Therefore, different accommodating spaces 4 are obtained through the steps S101 to S103, and the supporting effect of the second frame sealing glue 32 between the array substrate 1 and the color film substrate 2 is utilized to improve the overall uniformity level of the display panel and the optical performance thereof.
Preferably, the first frame sealing glue 31 is coated from the lower side edge of the color film substrate 2, the side edge of the DP side (lower side) of the color film substrate 2 is taken as the starting edge according to the glue frame area formed after the glue drawing, the first frame sealing glue 31 is sequentially coated from the starting edge to the other side edges, the second frame sealing glue 32 is coated after the second frame sealing glue 32 is coated to the position of the second frame sealing glue 32, finally the second frame sealing glue 32 is coated on the side edge positioned on the DO side, the uniformity of coating the frame sealing glue is ensured, and the frame sealing glue can be coated at the joint of the first frame sealing glue 31 and the second frame sealing glue 32 in an overlapping manner, so that the stable support of the second frame sealing glue 32 on the array substrate 1 and the color film substrate 2 is ensured. In this embodiment, the first frame sealing glue 31 is coated from the lower side edge of the color film substrate 2, and then the second frame sealing glue 32 is coated, and finally the first frame sealing glue 31 is coated on the upper side edge of the color film substrate 2 for sealing and closing, so that the coating time of the frame sealing glue can be effectively shortened, and the uniformity of the frame sealing glue coating can be ensured. Meanwhile, as shown in fig. 4, since the space of the lower side edge region of the color film substrate 2 is large (FPC etc. is arranged), the side edge on the DP side is used as the coating start edge, so that the glue coating amount and the like can be adjusted in time, and uneven coating caused by sudden glue discharge can be avoided.
In a specific implementation, since the widths of the first frame sealing glue 31 and the second frame sealing glue 32 are different, the second frame sealing glue 32 may be coated on the inner side of the first frame sealing glue 31 after the first frame sealing glue 31 is completely coated.
As shown in fig. 5, other manufacturing processes of the display panel, such as non-photosensitive negative polyimide coating (PI coating) rubbing alignment (rubbing), can refer to the prior art, and will not be described herein.
